How should chemical products be stored in a barber shop?

Chemical products should be stored in a cool, dry area out of direct sunlight to preserve their integrity and effectiveness. Exposure to heat or direct sunlight can cause chemical reactions that alter the products, potentially making them less effective or even unsafe for use. Storing them in a stable environment helps in maintaining their properties, reducing the risk of degradation and ensuring a safer experience for both the barber and the client.

The other choices compromise the safety and effectiveness of the products. Storing chemicals in the bathroom could expose them to moisture and humidity, which are not ideal conditions for maintaining product stability. Keeping them on a shelf above the shampoo bowl increases the risk of accidental spills or contamination. Storing chemicals in a hot area can lead to breakdown of the active ingredients, ultimately diminishing their effectiveness.
